A fluid having a viscosity u 9.35 x 104 lbf-s/ft is contained between two parallel plates, each of which has a cross section of 200 in2. The bottom plate is fixed whereas the top plate moves at a constant velocity of 4 ft/s when a shearing force is applied. The separation distance between the plates is a uniform 0.05 in. Assume the velocity distribution in the fluid is linear. Determine the following: 4. the shear stress in the fluid (lbf/in2)...
The velocity distribution for laminar flow between parallel plates is given by where h is the distance separating the plates and the origin is placed midway between the plates Consider a flow of water at 15° C, with umaz 1.65 m/s and h = 0.89 mm. Calculate the shear stress on the upper plate and give its direction. Use Table A.8 Ti N/m2 yr
Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates (Figure 3(a)). The top plate is moving at speed V, and the bottom plate is stationary. The distance between these two plates is h. The gravity acts in the z direction so the flow can be considered essentially two dimensional in x-y plane. Assume there acts an applied pressure gradient in the x-direction with its gradient given by, aP/ax (Po-P1)/(x2-x1)-constant, where x1...

A thin flat plate is placed in between two parallel plates (top and bottom) as shown in Figure Q1. The distance separating this thin flat plate with both parallel plates is h. Apart from having a stationary top plate, the thin flat plate is moving at the speed of U and the bottom plate is moving to the left at a velocity of 0.2U. The fluid in the upper flow region (above the thin flat plate) and in the lower...
Two parallel plates, each with zero mass and an area of 10,000 cm2 are set 0.1 mm apart and the space between them is filled with a Newtonian fluid. The upper plate is pushed in the direction shown with a constant force sufficient to accelerate a mass of 1 kg by 1 m/s2, which causes the upper plate to move with a velocity of 1 m/s relative to the lower plate. What is the viscosity of the fluid? Select the...
Q6. marks) Consider an electromagnetic flowmeter which is used to measure the average volumetric flow rate of a process fluid in pipe of 0.1 m diameter. The velocity profile is symmetrical and can be assumed uniform. The flux density in the liquid is 1.4 Wb/m2. The output from the fow meter is given to an amplifier of gain 10 and the internal resistance developed due to the fluid between the electrodes is found to be is 200 kf2. The input...
2. Consider a capacitor created when two identical conducting plates are placed parallel and close to each in other in vacuum The surface area for each plate is e.0400 m2. The two plates are separated by a distance of e.00200 m. When an electric potential difference of 5e.e v is established between the two plates, what is the magnitude of the electrostatic force between the charged plates? Is the force attractive or repulsive? 3. What mass on the Earth surface...
